Can't really manage it since I'm still in the process of reading Marx but: a community to give a leftist analysis of the macroeconomy. Also serve as a community to discuss modern trends in the field along with their issues (neoclassical and Keynesian). Maybe call it /political_economy instead of /economics
There was a previous request for the same comm by /u/Ectrayn , so there is definitely some interest as well as people who could mod it (myself included, I suppose)
